Comments on Charting App for Android

★★★★☆ Sam · Jan 3, 2012
Only App for Creighton Method Very customizable, would be nice if the info could be transferred to my fiancé and I wish it would allow more than a 2-month side by side comparison. Only real complaint is that it keeps reverting to an old cycle (from the demo version) when I get to the last few days in a cycle.
★★★★☆ A Google User · Jan 27, 2013
A lot easier than paper charting for me. :-)
★★★★☆ Kara · Nov 14, 2011
This has been a great app, much more convenient than the chart and stickers. I would give it five stars if it were able to print the temp chart.
★★☆☆☆ A Google User · Mar 17, 2014
Mediocre Works ok, but I would like to see some improvements. 1. It is hard to read the dates/info as the text/boxes are so small on my phone (smaller than screenshots shown). If there are multiple symptoms, I only see the first 6 letters of the first word. 2. On export to HTML it doesn't show each date on each day. It just shows a date range in the very first box. All days on one row so if you are planning to print this out the text will be small (not ideal – would prefer 15 boxes on each row or so). The HTML export does show all symptoms which is good. 3. It doesn't have all symptoms for the charting aspects of the full Creighton Model, but you can add any missing ones on your own. I took a picture off the back of a paper chart I had for the Creighton Model and saved it to my phone. Would be nice to have all that charting information included with the app. 4. To sync this app with another phone you export the data and then import it to other phone. You have to select the date range you want (so you have to make sure you get the right dates for what you want transferred over). This makes sense when exporting a cycle, so I can print it, but not ideal for copying all data to another phone.
